“Thirty-four percent of teens living in the U.S. own an iPhone, and 40 percent of those who don’t are expecting to buy one in the next six months,” John Paczkowski reports for AllThingsD.

“This according to Piper Jaffray’s 23rd semiannual survey of 5,600 American teenagers, which finds continued, rising interest for the device in the high-school demographic,” Paczkowski reports. “The percentage of teens who own an iPhone rose to 34 percent from 23 percent in fall 2011, and 17 percent in spring 2011. Meanwhile, the percentage of those who hope to own one rose from 38 percent and 37 percent during the same time periods.”

Paczkowski reports, “Thirty-four percent of the teens Piper surveyed said they already own a tablet, up from 29 percent from fall 2011. Of those, 70 percent had iPads, 19 percent some model of Android tablet and 11 percent a Kindle Fire. Among teens who don’t yet own tablets, 19 percent said they planned to buy one in the next six months, with 80 percent of that group saying they planned to buy an iPad.”

Apple continues to dominate in not just profit share, but also market share in the portable media player market… As with iPods, there are no third-parties (carriers) inextricably tied to tablets. The carriers are not the primary means for selling tablets as they are for smartphones. Therefore there is no one to foist pretend iPads into the hands of the ignoranti they way carriers currently do with Android phones and soon will do with Windows Phones. The iPad market is just that: The iPad market, not the tablet market. The iPad is much more like the iPod than iPhone.

Correction: 40% of teens plan TO HAVE THEIR PARENTS buy them an iPhone, 80% an iPad. And theres the rub, isn’t it? A great many parents are either unable or unwilling to drop that kind of cash on a teen. I know I wouldn’t.
